Accumulating evidence shows that the anti-cancer potential of the immune response that can be activated by modulation of the immunogenicity of dying cancer cells. This regulated cell death process is called immunogenic cell death (ICD) and constitutes a new innovating anti-cancer strategy with immune-modulatory potential thanks to the release of damage-associated molecular patterns (DAMPs). Some conventional clinically-used chemotherapeutic drugs, as well as preclinically-investigated compounds of natural origins such as anthracyclines, microtubule-destabilizing agents, cardiac glycosides or hypericin derivatives, possess such an immune-stimulatory function by triggering ICD...

Th17 cells are a specialized subset of CD4+ T cells that are essential in driving inflammation during autoimmune disease and infection through a signature cytokine IL-17. Th17 cells have been found in various human cancers. The function of these cells in cancers is highly context-dependent; both tumor-promoting and tumor-suppressing activity have been reported. IL-17 and IL-22, Th17-derived cytokines, influence the tumor microenvironment by directly promoting transformed cell properties and neighboring stromal cell activity...

Many efforts have been made to improve the efficacy of dendritic cell (DC) vaccines in DC-based cancer immunotherapy. One of these efforts is to deliver a DC vaccine more efficiently to the regional lymph nodes (rLNs) to induce stronger anti-tumor immunity. Together with chemotaxis, transendothelial migration (TEM) is believed to be a critical and indispensable step for DC vaccine migration to the rLNs after administration. However, the mechanism underlying the in vitro-generated DC TEM in DC-based cancer immunotherapy has been largely unknown...

Autophagy is an essential process for maintaining cellular homeostasis, a critical process in all cell types. Because neurons are post-mitotic cells, maintaining cellular and functional homeostasis is more important in neurons than in other types of cells. Synapses are fundamental units needed for neural communication, and synapses with consistent protein quality are essential for neural functionality. Dysregulation of autophagy in neurons has been shown to be related to neurodegenerative diseases, including Alzheimer's disease and Parkinson's disease...

Mitochondrial dysfunction caused by oxidative stress appears at early stages of aging and age-related diseases. Plasma membrane redox enzymes act in a compensatory manner to decrease oxidative stress and supply reductive capacity to ensure cell survival. Plasma membrane redox enzymes transfer electrons from NAD(P)H to oxidized ubiquinone and α-tocopherol, resulting in inhibition of further oxidative damage. Plasma membrane redox enzymes and their partners are affected by aging, leading to progression of neurodegenerative disease pathogenesis...

Hydrogen sulfide (H2 S), a gasotransmitter molecule, has attracted attention as an endogenous signaling molecule because of its various pathological and physiological effects, including pathologies related to aging. In this review, we aimed to discuss the morphological changes in each vessel following aging, and to evaluate the possible role of H2 S in the cerebrovascular alteration, such as arterial stiffness, microvessel loss, and blood-brain barrier disruption, with advancing age. Additionally, the review outlines the therapeutic efficacy of the H2 S-releasing compounds on the cerebrovasculature...

Natural killer (NK) cells are innate lymphoid cells that provide early protection against cancer development via their selectivity to kill abnormal cells undergoing cellular transformation without the need for prior stimulation. Given the correlation between NK cell dysfunction and cancer prognosis, restoration of endogenous NK cells in the tumor microenvironment or adoptive transfer of NK cells with improved function holds great promise in cancer treatment. Furthermore, MHC-unrestricted tumor lysis by NK cells complements the MHC-restricted killing of tumor cells by cytotoxic T cells, thus positioning NK cells as an alternative or complementary therapeutic target for cancers that are refractory to T cell-based therapy...

RH1 (2, 5-diaziridinyl-3-(hydroxymethy)-6-methyl-1, 4-benzoquinone) is a bioreductive anticancer drug. The mechanism underlying its therapeutic properties has not yet been elucidated. In this study, we aimed to determine whether RH1 exerts its anticancer effect via p53-mediated apoptosis and senescence in vitro and in vivo. RH1 displayed dose-dependent biphasic effects in vitro, i.e., it induced apoptosis at higher dose and senescence at lower dose accompanied by marked activation of p53. Thus, RH1 primarily induced cell death by apoptosis...

Currently, coronary artery disease accounts for a large proportion of deaths occurring worldwide. Damage to the heart muscle over a short period of time leads to myocardial infarction (MI). The biological mechanisms of atherosclerosis, one of the causes of MI, have been well studied. Resistin, a type of adipokine, is closely associated with intravascular level of low-density lipoprotein cholesterol and augmentation of the expression of adhesion molecules in endothelial cells. Therefore, resistin, which is highly associated with inflammation, can progress into coronary artery disease...

Cancer immunotherapy has emerged as an effective therapeutic strategy to treat cancer. Among diverse immune populations, invariant natural killer T (iNKT) cells have shown potent antitumor activity by linking innate and adaptive immune systems. Upon activation by lipid antigens on CD1d molecules, iNKT cells rapidly produce various cytokines and trigger antitumor immunity directly or indirectly by activating other antitumor immune cells. Administration of a representative iNKT cell ligand alpha-galactosylceramide (α-GalCer) or α-GalCer-pulsed APCs effectively stimulates iNKT cells and thereby induces antitumor effects...

Neuroinflammation plays a role in cancer chemotherapy-induced chronic pain. Thus far, most studies have focused on neuroinflammation suppression. However, there are limited reports of which factor is involved in the transition from acute inflammation to chronic inflammation, resulting in neuroinflammation and chronic pain. Here, we compared the inflammatory reaction and pain response induced by LPS and paclitaxel. LPS (0.5 mg/kg) or paclitaxel (2 mg/kg/day for 5 days) was administered intraperitoneally to mice, and mechanical allodynia was examined by von Frey test...

Immune checkpoint inhibitors (ICIs) such as anti-PD-1 and anti-CTLA-4 therapy are now FDA-approved treatment options for different cancer types. However, the therapeutic efficacy of ICIs varies substantially among cancer types and patients, and only a limited proportion of cancer patients benefit clinically from ICIs. To improve the therapeutic efficacy of cancer treatments involving ICI, the mechanisms of response to ICIs and the heterogeneous pattern of immune checkpoint receptor expression need to be better understood...

The α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) is a major glutamate-gated ion channel in the brain and is important for synaptic transmission, synaptic plasticity, and learning. Palmitoylation, a post-translational modification, is a critical process regulating AMPAR trafficking, synaptic function and plasticity, and learning and memory in health and diseases. In this review, we discuss current knowledge on the palmitoylation-dependent regulation of AMPAR trafficking and functions...

Obesity is one of the worldwide prevalent disease caused by the imbalance between food intake and energy expenditure. Over a 100 years of research demonstrate that hypothalamus is the critical brain region regulating energy homeostasis, and evidences suggest the participation of non-neuronal populations such as astrocytes and microglia in the regulation of energy homeostasis. Recently, fat-rich diet induced hypothalamic inflammation has been found to deregulate the energy homeostasis, leading to the insulin resistance, glucose intolerance, and obesity...

Engineering T cells with a chimeric antigen receptor (CAR) that reprograms their antigen selectivity and signaling has recently emerged as one of the most promising therapeutic approaches for treating cancers. For example, two CD19-specific CAR T cell (CAR-T) therapies have shown remarkable responses in patients with relapsed/refractory B-cell cancers, and were approved by the US Food and Drug Administration in 2017. This initial clinical success has spurred an explosion of interests in this novel therapy from both academia and industry, and results from basic and clinical research have enabled the rapid evolution of the CAR-T field...

Glial cells outnumber neurons in the brain and play important roles in the neuroinflammation that accompanies brain damage in neurodegenerative diseases. In Parkinson's disease (PD), dopaminergic neuronal loss is accompanied by inflammatory changes in microglia, astrocytes, innate immune cells, and infiltrating peripheral immune cells. Neuroinflammation is probably a fundamental immune response to protect neurons from harm and compensate for neuronal damage, but at the same time, its neurotoxic effects exacerbate neuron damage...
